Q: How do I test to see if my gas valve on my wall heater is working or not? Please don't respond and say call a pro.: Depends on what kind of wall heater. FOR A 24 volt system : you will need a ohm/volt meter to do that. Make sure the thermostat is calling for heat, and the gas going to the unit is on. you should have 24 volts at the gas valve. if there is 24 volts there, and the burners are not on, then the gas valve is bad. If you don't have 24 volts there, then your thermostat could be bad, and not turning on the gas valve, or you might not have control voltage. You should be familiar with basic electricity to do this.

Q: A reading from my 2002 ford explorer said insufficient flow from the EGR valve. Would it be possible to clean the valve or fix it or would I need to buy a whole new valve?: It could be two things. The exhaust gasket coming to the valve or the vacuum coming to the valve. The egr did not need changing. Without the proper tool to check it out. I can not say which it is or how to repair. It need to go to shop where the proper test can be use to find what need to be repaired of replaced Most likely it will be a one way vacuum valve, that is not working right.

Q: i have a mitsubishi eclipse 1993 and its running too lean my old smog paper said the hc's (hydrocarbons) are too high. would a egr valve temp sensor make it do that if its fualty? or could it be someting else?: A faulty EGR sensor or the EGR valve itself would definitely make the car run lean at idle. The sensor regulates the amount of EGR opening at various coolant temperatures and manifold vacuum if it's vacuum actuated. If the diaphragm under the EGR valve has ruptured you'd get a straight vacuum leak plus lean condition if vacuum actuated. There's a simple test for EGR valves. Place a length of tubing on the valve port and dray vacuum with your mouth. Reach under the valve till you feel the rubber diaphragm. If the valve opens you'll feel it with your fingers. If it doesn't move the diaphragm has a hole in it.

Q: I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:: A blow off valve releases the air into the atmosphere which gives you the noise their known for. A bypass valve releases the air back into the intake, like a stock BOV on most turbo cars including the WRX they are also known as recirculating BOV's, and do not produce the sound that a atmospheric BOV will make. A recirculating BOV will not cause you to run rich, and thats why a lot of people recommend them unless you are running a bigger turbo/ lots of boost. However they do not always make you run rich, and i would suggest that if you do get an BOV to just install it and not mess with it. If you mess around with the spring on them it can cause compressor surge which you do not want. However, I have used the hks ssqv with none of these problems.

Q: I have a 40 year old Holton Bb trumpet. It plays fine except the first valve always gets stuck when I play it, in the middle of a song it won't come back up. I can pull it back up and it doesn't get stuck real bad, but how can I fix this? I always oil it properly and insert the valves right. Do I have to replace it? Thanks: You need not replace the valve, but it does need a bit of attention. There are many possible reasons for the sticking and you can spend a long time trying to chase them down. Inconsistent sticking suggests 2 likely reasons (there are several more possible reasons). The first is piston wear that has slightly misshapen the valve casing so it sticks because it doesn't travel through the valve casing exactly the same way every time. The second is that the felts and corks are worn and need to be replaced. The best thing for you to do is to take it to a shop, describe the problem and spend a few bucks to get it fixed right.

Q: i have been having these chest pains and i went to the doc. they did an ekg, blood test for enzymes and a echo. Well today i went back for the results of the echo and was told that i had a leaky valve but it was nothing to worry about and that there are just trace amounts of valve regurgitation. Im only 19 and i have no other history of heart problems or diseases should i be worried...they said i didn't need any anti biotics or anything and that it wouldn't kill me just to watch for it as i age into my latter years of life 50-70, but im still kinda worried..anyone else have this? im also pregnant and im concerned as to how this will affect my pregnancy, labor and delivery????: well, firstly, almost everyone has trivial valve regurg. it is considered okay and not a need to be alarmed by it. its the severity that matters most. so i see that u have a valve regurg but just trace amounts so it should be alright. this may well due to your pregnancy, (just a possible cause) that u get this but it may also be all along even before pregnancy. it doesnt affect your pregnancy much unless u have hypertension. it is called hypertensive pregnancy. this is much attention needed than your current trivial regurg. but do go for another scan after pregnancy to make sure that the regurg doesnt worsen. the bottomline is... dont worry. you're doing okay. happy pregnancy! :)

Q: ok im 17 and had really bad chest pains for like 2 years and the dr told me last year my valve was leaking and the pains have been getting worse what should i do?: Your doctor should have referred you to an heart specialist. Don't be asking kids here, ask the doctor!

Q: Is it safe to remove the butterfly valve on my 94 celica 1.8l st?: Why would you want to do that? The butterfly valve is a very important part of your engine. It is what gives your foot the ability to control engine RPM's. Therefor don't be stupid and mess with something that you will possiblly regret later

Q: I have a 97 ranger 4.0L that takes 10w-30 and I'm going to be changing the oil soon. It has some valve clatter I'm just wondering if I can use a thicker oil such as 15w-30 or maybe a 10w40?: 10W40 works fine. That's all I've ever run in my Explorer - and presently it has just under 200,000 miles.

Q: I've been diagnosed with mitral valve prolapse, my doctor just told me that i need to setup an appointment with the hospital to look at treatments for heart mitral valve prolapse-to possibly have a heart valve replaced. I am wondering if i should setup an appointment with mayo clinice in minnesota to get another opinion on that? I'm wondering if surgery is an only option available to me, i have been taking beta blockers that have been no help for the past 3-4 months. Thanks.: was this diagnosis made by a cardiologist? You said your doctor - are you referring to your primary MD. I am going to assume the MVP diagnosis was made by a cardiologist . the referral to the hospital - is this to a cardiac surgery program at the hospital. You may definitely want to get a second cardiology opinion. Do you live near the Mayo clinic? You also have to consider your health care insurance and what they will cover. It sounds as if your MD is sending you in the appropriate direction - to a hospital - to look at treatments. Can you call this hospital to find out more about the services to which you are being referred?
